Spccication forming part of Letters Patent No. lalld, dated November 22, 1.864.

To all whom, it may concern:

Be it known that I, LEwIs BooRE, of the city ofBuft'alo, county orn Firie,and State of New York, have invented a certain new and Improved SolderingFurnace5 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompaliying drawings and the letters ot' reference marked thereon, in which- Figure l is a vertical section, and Fig. Il is a top plan, of my improved furnace.

The nature ofthis invention consists in such relative combination and arrangement of the coal-chamber, smokeiiue, grate, hearth for the irons, and draft-openings as that the air for combustion will enter the coal-chamber above the irons and pass downward onto the irons through the grate and into the smoke-flue, whereby several beneficial results are accomplished.

Letters of like name and kind refer to like parts in each ofthe tigures.

A represents the coal-chamber, which is represented ot' a semi-cyli ndrical cross-section, but which may be made square or of any convenient form.

B represents the grate, forming the bottom of the coal-chamber.

(l represents an ashpit, for the reception of the ashes as they fall through the grate 5 C', door to ash-pit.

D represents an opening into the coal-chamber, through which the soldering-irons areinserted. The bottom of this opening is even with the grate.

E represents a hearth projecting from the coal-chamber from around the opening D. The bottom of the hearth starts even with the grate but, inclines upward in a manner to prevent the ashes from falling out, and form a proper support for thesoldering-irons.

E represents a hinged iiap or cover to the hearth, which when thrown up, allows the in l sertion ofthe solderingirons, and when shut down lits closely to the shanks otA the solderi ing-irons in a ina-nner to prevent the entering ot' air into the furnace through the opening D.

F represents the draft-opening, located just above the hearth. itis provided with a damper, F', by which the size ot' the opening is regulated.

G represents a chamber formed at the back of the furnace, so as to open above and below the grate.

E represents the smoke ilue, leading from the chamber G.

G is a damper, connected to the back edge ot'the grate, by which the opening into the chamber G may be closed so as to cause the draft to be entirely downward through the grate; but when starting the lire and a more direct draft is desired it may be left open 5 Il', damper in smoke-fine.

In consequence ofthe draft being downward the coal in the chamber A cannot become ignited above the draft-opening F, while that below the draft-opening and on the irons will be all aglow. The body ot' coal in the chamber above acts as a consta-nt. feeder by its own weight as the ignited coals are reduced to ashes. The tire is thus made to maintain and give a very uniform and constant heat, with little or no trouble to the user.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

rlihe relative arrrangement and combinatio ofthe coal-chamber A, draft-opening F, heart E for the soldering-irons, and smoke-flue H as that the air for combustion will enter above and draw down onto the soldering-irons, for the purposes and substatially as described.
